Box-STRIKE ron Locks,

Patenten tray e, raie.

Application led January 12, 1914. Serial No. 811,723.

To all rcito/m t may concern Be it .known that l, WILLIAM N. THOMAS, a citizen of the United NStates, residing in New Haven, county of N ew Haven, State of Connecticut, `have invented certain new and useful Improvements in 'Box-Strikes for Locks, of which the following is afull, clear, and exact description. 'Y rThis invention relates to box strikes for locks, and its primary object is to provide a box strike particularly adapted for locks havinga latch bolt and a dead bolt, which box strike `is reversible so that it can be used in"l connection with an inwardly swinging door or an outwardly swinging door. `More particularly, it is aimed to .provide a box'strike of thekind stated, in

which the box portion may be applied to the plate portion at either face of the latter so that when the parts are properly assembled the laterally projecting lip for the latch bolt may project outwardly from thedoor frame when the door is to swing outward, or inwardly from the door frame when the door is to swing inward, without the necessity of inverting the lock on the door.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafterk described and claimed.

ln the vaccompanying drawing, Figure yl is a front elevation of a box strike embodying my improvements, Fig. 2 is a rear elevation of the same.` Fig. 3 is an edge View of Fig. l, looking from the left, Fig. l is a similar view showing the strike reversed, z'. e., with the box portion at the opposite face of the plate, and Fig. 5 isa section on line 5-5 of Fig. 1.

Referring to the drawing, the box strike consists of the main or plate portion 6 and the box portion 7. The plate 6 is provided with screw holes 8, which are countersunk at both ends, so that when the strike is applied to the door jamb with either face outermost, the heads of the attaching screws will lie flush with the outer surface of the plate. The plate'is also provided with a latch bolt opening 9, a dead bolt opening 10, and laterally projecting flange or lip 11, associated with the latch bolt opening. The box portion 7 of the strike is detachably secured to the plate portion by means, such as the screws 1:2. This box portion is preferably constructed ofv sheet metal, as

distinguishedy from the cast metal from which the plate portion is preferably constructed. fin-the form shown, the box portion is made from a single sheet metal plate or blank, suitably bent up into box-like form, and having flanges 13 at the respective ends by means of which the box portion is secured to the plate, the screws l2 being passed through the flanges 13, preferably in the manner shown in Figs. 2 and 5. At the rear of the strike, the screws 12 are provided with nuts lai. `The screw openings 15 in the plate 6, through which the screws l2 are passed, are countersunk at both faces of the plate, so that when the box portion is applied to eitherface, the heads yof said screws will lie flush withy the outer surface of the strike. The box portion may be readily removed from the plate by unscrewing the screws l2, theheads of which are provided with the usual screw drivernicks. Ilnthe particular form shown, the nuts 14 are of rectangular shape and so yarranged that one side lies against, or in close proximity to, the adjacent wall of the box portion, as shown in Fig. 5, whereby the nut is prevented from turning as the screw is turned by the screw driver. Vhen the box portion has been` detached from` one side of the plate, it may be readily applied to the other side of the plate in the same. relation, so that the strike may be adapted to eitheran inwardly swinging door or an outwardly swinging door. The two different adjustments are shown in Figs. 3 and l respectively. -lt will be obvious that in the case of a lock having a-latch bolt and a deadfbolt, an ordinary box strike if constructed for an outwardly swinging door will not serve in the case of an inwardly swinging door unless it is inverted, and this makes it necessary to invert the lock on the door which is very inconvenient and objectionable, even when practicable. By my improvements, however, this disadvantage is entirely obviated. rlhe` plate 6 may be readily placed on the door frame with the lip 1l projecting outwardly for an outwardly opening door), or it may be turned over in a horizontal plane and placed on the door frame with the lip 11 projecting inwardly (for an inwardly *opening door). In one case, one face of the plate 6 is outermost, and in the other case, said face is innermost, but, in both cases, the box portion is so located as to form a closureback of the bolt openings in the mortise cut in the ldoor frame.

Without llimiting myself to the construction shown, I claim l. A strike for locks, comprising a plate having a plurality of boltV openings and a laterally projecting latch bolt lip associated with one of said openings, av box portion formed and adapted for location back ot' one of said openings, and means for securing said box portion in position at Yeither face of said plate; substantially as described.

2. A strike for locks, comprising a plate having a plurality of bolt openings and a laterally projecting latch bolt lip associated with one of said openings, a box portionv adapted to form a closure back of all of said bolt openings, and screws for securing saidy box portion in position at either face of said plate; substantially as described.

3. A strike for locks, comprising a plate portion having a plurality of bolt openings and a laterally projecting latch bolt lip associatedl with one of said openings, said plate also having screw openings therein countersunk on opposite faces of the plate, a box portion applicable to either face of said plate portion, and means for holding the ,plate portion and box portion in assembled relation; substantially as described.

4t.. A box strike, comprising a plate portion having a plurality of bolt openings and a laterally projecting latch bolt lip associated with one or' said openings, said plate portionjalso having screw openings countersunk on opposite faces thereof, a box portion having a rim to engage either face of said plate portion, and means to secure said box portion infposition at either faceot' saidy plate portion whereby the latch bolt lip may project outwardly from the door frame for an outwardly opening door, or inwardly from the door trame for an inwardly opening door, without the necessity of inverting the strike; substantiallyas described.

Y 5. In a reversible box strike, the combination of a plate portion having a latch bolt` Copies of this patent may be, obtained for opening with an associated flange or lip and a dead bolt opening, said plate portion adapted to be morti'sed Yin the jamb of the door with either face outermost, and Closure means located back of said bolt openings and applicable to either face of said-plate portion whereby said strike may be reversed without changing the relation ot' the bolt openings; substantially as described.

6. A reversible box strike, comprising a plate portion having openings at opposite ends for the passage of screws to secure it to the door jamb, said screw openings being countersunk at both faces of said plate por tion, said plate portion having a latch bolt opening with an associated flange or lip and a dead bolt opening, a box portion having a flanged rim and located back of at least one of saidV bolt openings, and a screw for holding the flanged rim of said Vbox portion in contact with the plate at either tace of the latter whereby the strike may be Vreversed and adapted to an inwardly swinging door or to an outwardly V,swinging door by turning said plate portion face for face, and changing the box portion from one face to the other without changing the relation of,

the bolt openings; substantially as described.

7. In a reversible box strike, the combination of a plate portionlhaving screw. openings countersunk on opposite faces thereof, said plate portion having a latch bolt opening with an associated lip orvliange and a dead bolt opening, a box portion extending y back ot' both bolt openings, and provided wi h end flanges disposed at the same face of the plate las the box portion proper, and means `to secure Vsaid flanges detachably to said plate portion at either face of the latter, whereby ythe strike may be adapted to an inwardly swinging door orto an outwardly swinging door without inverting the bolt f openings; substantially as described.

In witness whereof, I have hereuntok set my hand on the 9th day of'January, 1914i. y
